Heat accumulating material

Abstract

Abstract PURPOSE: To prepare a heat accumulating material suitable for the heat source of a heat pump, by adding strontium oxide or barium oxide to a heat accumulating material containing CaCl 2 .6H 2 O or CaBr 2 .6H 2 O, thereby extremely efficiently preventing the supercooling of the heat accumulating material. CONSTITUTION: A heat accumulating material containing CaCl 2 .6H 2 O and/or CaBr 2 .6H 2 O is compounded with strontium oxide or barium oxide as a supercooling preventing agent pref. in an amount of 0.01W1wt%. The supercooling of the composition composed of CaCl 2 .6H 2 O added with strontium oxide or barium oxide is broken at ≥23°C. EFFECT: The molten liquid is neutral, low corrosive, and available at a low cost. COPYRIGHT: (C)1982,JPO&Japio
